Ticket feeding mechanism The mechanism by means of which the ticketmaterial is advanced from the supply roll to and through the machine tothe point of cut-off willfirst be described, after which the mechanismfor making impressions on the tape at various points along its path oftravel will be explained in detail.

Referring to Fig. 4, the ticket tape I0 is fed from a spool II throughan arcuate guide l2. The tape is provided with notches I3 (as shown inFigs. 16 and 17), disposed along the edges at regularly spacedintervals, the distance between any two successive notches being thelength of the ticket to be prepared. From the guide I2 the tape I8passes pairs of rolls l4 and IS in succession, thence to printingplatens I6 and I1 to the position shown in Fig. 21 where' the leadingedge is at the point of cut-01f designated I8. This position of the tapeis also shown in Fig. 1 and in Fig. 21 the short vertical lines crossingthe tape I0 indicate the limits of the successive tickets. With the tapein the position of Fig. 21, printing of the destination, price, andclassification is effected, after which the ticket is retracted to theposition of Fig. 22 wherein the date is printed on the ticket at platenl1. At the same time, the serial number is printed at platen I6 on the.next following ticket. Thereafter, the tape is moved. to the positionof Fig. 23 where the ticket is cut off at the point I8. The mechanismfor shifting the tape to these various printing positions will now bedescribed in greater detail.

Referring to Figs. 6 and 9, a pulley I9 is driven from any suitablesource of power, such as an electric motor (not shown), by means of abelt 20. Integral with the pulley is a clutch driving element 2|, which,with the pulley, is loosely mounted on shaft 22. When a ticket is to beprinted, clutch magnets 23 are energized to attract armature latch 24and permit spring-pressed dog 25, pivoted to arm'26, to engage thedriving element 2|. Arm 26 is secured to the shaft 22 and, accordingly,the shaft will now be rotated. As will be explained hereinafter inconnection with the circuit diagram, the energization of the magnet 23is not maintained so that shortly after energization it releases itsarmature latch 24, permitting the arm to drop back into the path of thedog 25 so that upon completing a single revolution of shaft 22, theparts become disengaged and resume their normal relationship, as in Fig.9.

Referring now to Fig. 1, the shaft 22 carries a bevel gear 21 meshingwith a similar gear 28 on a shaft 29 (see also Fig. 3). The shaft 29carries a gear 30, which meshes with a gear 3|, which in turn causesoperation of shafts |5a and Ma upon which the lower printing wheels I5and I4, respectively, are mounted through the medium of gears generallydesignated 32. v Gear 3| also drives a gear 33 which in turn, throughthe medium of gearing 35, drives the shafts |5b and I4!) upon which theupper printing rollers I5 and I4, respectively are mounted. The shaft|4b carries a gear 35 which, through a pinion 36, drives the shaft uponwhich inking roller 3'! (Figs. 1 and 4) is mounted. A similar inkingroller 38 is provided for the printing rollers I5 and may be driven in asimilar manner.

Between the arcuate guide I2 and shaft I411 is a rod 39 (see also Fig.2). Secured to the rod are members 40 which are straddled by fingers 4|which are pivoted to the members 40 at their lower ends and are normallyurged apart by a spring 42. The upper extremities of fingers 4| areprovided with hooks 43 which are adapted to engage in the notches |3 inthe tape to effect accurate alinement of the same. Pivoted to the frameof the machine (see Fig. 1) is a pair of fingers 44 pivoted at 45 andprovided with a pin and slot connection 46 so that rotation of one ofthe fingers will cause concurrent rotation in the opposite direction ofthe other finger. When the fingers are moved together, they will urgehooks 43 into engagement with the edge of the tape and when they aremoved apart, the hooks 43 are free to move away from the edges of thetape under the influence of the spring 42. Integral with one of the arms44 is an arm 41 connected by a link 48 to a bell crank 49 (see Fig. 4)whose one arm carries a roller in engagement with a cam 50 carried byshaft I4a. On the same shaft is a cam 5| which cooperates with afollower arm 52 secured to the shaft 39. The operation is such thatafter printing of the destination, price, and classification has beeneffected on the leading ticket section, cam 50 operates to cause fingers4| to engage in the notches I3 standing opposite the fingers andthereafter cam 5| will rock shaft 39 counterclockwise as viewed in Figs.4 and 22, whereby the tape will be retracted from the position of Fig. 1to that of Fig. 22. Thereafter, the fingers 4| are moved away from thetape and returned to their initial position.

I During the movement of the tape I0 toward the left, under control ofthe fingers 4|, the tape is free of the pairs of rollers I4 and I5. Asis shown in Fig. 21, the upper roller I4 is provided with type onslightly more than half its circumference, this type being arranged toefiect the printing shown in Fig. 16. The lower printing roller I5carries the type for printing the face of the ticket as in Fig. 17, withthe exception of the variable information. In Fig 21, the upper rollerI4 and the lower roller |5 have just advanced the tape to properposition for printing the destination and at this time the raised typemove out of engagement with the tape so that there is now no contactbetween the rollers. During the interval that the type rotates from theposition of Fig. 21 to that in Fig. 22, the classification data areprinted and the tape is retracted to receive the number and dateprinting, after which time the type faces will arrive in the position ofFig. 22

and again pick up the tape to advance it the distance necessary to ejectthe completed ticket.

In Fig. 20 is shown a usual numbering device, indicated generally at 53,which is reciprocal in guides 54 and has the usual plunger 55 inengagement with a roller carried by a bell crank 56 which has linkconnection 51 with a follower arm 58 which is operated by a cam 59carried on shaft 22 (see also Fig. 1). A similar cam 60, also carried onshaft 22, serves to operate the dating deand link connection Ill to afollower arm 92 which vice which cooperates with platen IlI. At point l8there is provided a knife 6I (see Figs. 1 and 5) which is pivoted at 62and has connection with a bell crank 63 which, in turn, is connected bya link 64 to a bell crank follower arm 65 operated by a cam carried byshaft I511. At the proper time in the cycle of operations, the knife GIis rocked clockwise (as viewed in Fig. 5) to shear the completed ticketfrom the following portion of the tape.

Destination printing mechanism Printing of the destination is effectedon the ticket by means of type carried by a constantly rotating set ofwheels. As particular type characters pass printing position, printinghammers are rapidly impelled against the type to take an impressiontherefrom without interrupting the movement of the-type wheel. In Fig. 7is shown the type wheel from whichthe impressions are taken. These typewheels are .of three kinds. The four to the right, designated 61, areemployed to'print the price. The single wheel on the left, designated68, is employed to print the classification;' and the group of fourteenwheels 69 are employed to print the destination. The last set of wheelswill now be described, after which the'other two types will beexplained;

also Fig. 6) The shaft carries a pinion H which, through an idler I2, isdriven by gear I3 carried by the shaft 22. The type wheels 68 are thusdriven at a rapid rate, completing a full revolution during somewhatless than half a revolution of shaft 22.

Referring now to Fig. 5, there is provided. a printing hammer 14 foreach of the type wheels 6t and one also for each of the type wheels 61.A special hammer Ila is provided for the type wheel 68 which differsfrom the hammer ll in that it has a longer striking face. ,All of thehammers are freely pivoted at 15 and normally held in the position shownin Fig. 5 by springs I6. Mounted on a shaft 11 which is driven fromshaft IE through the train of gearing generally designated I8 areratchet-shaped driving wheels IQ of which there is one provided for eachtype wheel. In line with each wheel I9 is a, hook 80 pivoted at itsupper end to a lever BI and having its free end spring-presssed againsta by-pass latch 82 of a pivoted member 83. The member 83 is springurgedin a clockwise direction and normally held against such movement by alatch at which has link connection 85 with armature 85 of a magnet 8-1.Energization of magnet M will attract its armature 88 drawing link 85downwardly to rock latch 84 counterclockwiseand release lever $3. Thelever will thereupon rock hook at counterclockwise about its pivotcausing the tooth thereon to move into the path of the teeth of thedriving ratchet I9. The driving teeth will cause rapid downward movementof hook 8t and through lever SI the associated hammer it will be given arapid,

counterclockwise propulsion against the type wheel. Near the end of thedownward movement of hook 86 its free end will strike the fixed cam-'ming surface 88 and will disengage it from the driving wheel l9.

The particular character to be printed from any wheel is determined bythe timing of the operation of the printing hammers It and the circuitsand mechanism for effecting this timing will be explained in connectionwith the circuit diagram. The levers 83 are restored by means of a bail89 pivoted at 90 (see Fig. 6). The shaft 96 has lever is operated by acam 93 on shaft 22. The latches 84 are restored by-means of a bail 94secured to a shaft 95 which in Fig. 6 has lever and link connection 91to a follower 98 which is operated by a cam 99 also secured to shaft 22.

Price printing wheels The price printing wheels 61 of Fig. '7 areloosely mounted on the shaft Ill and are sector-shaped as shown in Fig.5, Integral with each sector til is a pinion IIIIl which meshes withrack teeth in a vertical link It I. The lower extremity of each link IGIis also provided with rack teeth meshing with a toothed segment I02which is secured to a pivoted plate I03 which is normally urged in aclockwise direction by a spring IM. A bail I05, secured to shaft I06,normally holds the plate in the position shown and is operated to causerotation of the price wheels 6'! through mechanism which comprises aspring-pressed arm Ill'I secured to shaft IIJB (Fig. 6), which arm haslink connection I08 to an arm I09 secured .to a shaft IIII. The shaftIIO carriesa follower arm III cooperating with acam i I2 carried byshaft 22. g

. connections :85 from the printing magnets associated with the pricewheels also have piv- 1 ot d on ction th' bell crank levers H3 which Thewheels 69 are secured upon a shaft I (see 7 e n in Fig. 5, .the trailinghigh portion of the same engages the latch II to rock it into latchingengagement with the bell crank I I 3. With the construction described,the teeth I I6 successively pass the engaging toe of latch II5 ascorresponding type elements on the price wheels 51 pass printingposition. Energization of an associated magnet 81 will rock bell crankII3 to release the latch II5 which will thereupon engage one of theteeth I I6, stopping the type wheel with a selected type in printingposition. At the same time, the related link 85 will trip theprintinghammer as hereinabove described so that stopping of the wheeland tripping of the hammer are concurrent operations. The reason forconstructing the price printing wheels'in the manner described andproviding mechanism therefor different from that for printing thedestination is to enable an accumulation to be made of the prices sothat the total amount of money involved in the several transactions maybe accumulated. This accumulating mechanism will be described later.

Classification printing The classification wheel 68 (Fig. 8) is providedwith nine printing faces and as these faces are of considerably greaterlength than the faces of the type from which printing is effected inflight, it is desirable that an impression be taken with the .wheel atrest. For this reason, a form of Geneva drive is provided which includesa star wheel EI'I which is integral with Wheel 68 and both are freelymounted on the shaft I0. Cooperating with the wheel II'l is a drivingpin I I8 carried by an arm M9 on a rod I20. The other end of the rod I20carries a pinion IZI (see Fig. 6) Which meshes with a. gear I22 drivenfrom the chain of gearing 18 so that the wheel iifi-advances constantlywith a step-by-step movement as the destination wheels 69 advance with acontinuous movement. The printing hammer Ma for the wheel 63 is trippedin exactly the same manner as the hammers I l and the timing is arrangedso that the hammer is tripped during the period when the wheel is atrest, the particular face printed from depending on the time at whichthe hammer is tripped.

Restoring means is provided for the latches I I 3 which comprises a bailI23 (Fig. 5) carried by shaft I24 (Fig. 6) which has lever and linkconnection I26 with a follower I21 operated by a cam I28 carried byshaft 22.

Extending over the printing wheels is an inking ribbon I29 which is fedfrom a spool I30 to a pair of. feeding rollers I3I, the larger of whichhas associated therewith a ratchet and pawl mechanism generallydesignated I32, which are operated through a link I33 connected at itslower extremity to the bail I05 so that for each operation of the bailthe ribbon is slightly advanced.

Key mechanism The selecting keys are shown in Figs. 10, 12, and'l3.These keys constitute levers I34 which are pivoted on rods I35.Connected to each key lever I34 at I36 is a bar I31 normally urgedupwardly by a spring I38. Each key lever I34 has pin and slot connectionI39 with the operating arm I40 of a counter mechanism I4! of the wellknown Veeder type so that each key lever operation will be separatelycounted. In Fig. 10, each key lever I34 and its corresponding counterI4I has located adjacent thereto an indicating marker I42 whichdesignates the destination,

price, and classification assigned to the particular key. Thus, thelowermost left hand marker I42 in Fig. 10 indicates that its key leverI34 controls the preparation of a one way ticket to Albany, whose priceis $3.45.

Cooperating with all of the key levers I34 is a horizontally slidableplate I43 having notches I44 through which the key levers I34 extend.Extending into each notch is a cam latch I45 against which the operatedkey lever acts to cause the plate I43 to be shifted toward the left asviewed in Fig. 10. The plate has connection with a link I46 which isprovided with an extension I41 (see also Fig. 12) which operates a pairof contacts I48. As the plate I43 is moved toward the left as aconsequence of the operation of one of the key levers, the extension I41will close contacts I48. These contacts control the initiation of. acycle of operations of the machine during which the ticket is preparedand ejected. Secured to each of the bars I31 is a plurality of contactplates I50 which are suitably insulated from one another and from thebar I31 (see Fig. 11) The number of plates I50 connected to each bar I31is dependent upon the number of letters in the destination and thenumber of figures in the price to be printed under control of therelated key. For example, the bar I31 associated with the Albany key hasplates I50 secured thereto which are separately shown in Fig. 18. Theleft hand plate will control the printing of the designation One way;the next six plates will control the printing of the destination Albany;the next one will control the printing of the dollar sign; and the lastthree will control the printing of the digits of the amount. Each of theplates I50 has a pair of steps I5I located at various levels inaccordance with the character to be' printed. These steps are arranged,when the supporting bar I31 is lowered, to complete electricalconnections to the printing magnets to select the various characters atthe proper time in the operation of the machine. Extending across all ofthe bars I 31 in a single row are pairs of springs I52 which areanchored at their extremities to plug sockets I53 and I54. These springslie beneath the steps I5I and are normally out of contact therewith.When any bar I31 is shifted downwardly, all of the related steps I5Iwill make electrical contact with the related springs I52 so that eachplate will connect a spring I52 on one side of the bar with a spring I52on the opposite side, which is either in the same or a differenthorizontal plane.

The circuit connections established may best be understood from thecircuit diagram in Fig. 19 wherein the springs I52 on one side of thebars are shown as horizontal lines extending between the sockets I53 andI54. and the wires on the opposite side are shown as a separate setdirectly below. The plates I50 are represented as vertical lines makingconnection between one of the upper set of springs I52 and one of thesprings I52 of the lower set. Each of. the springs I52 of the lower setis' connected by a wire I55 to one of the printing magnets 81, theuppermost spring being connected to the printing magnet 81 whichcontrols the printing of the classification data derived from theprinting wheels 68 of Fig. '1. The lowermost four springs are connectedto the magnets 81 which control the positioning of the numerical typesectors 61 while the intervening group control the magnets which printfrom the constantly rotating type wheels 69. The connections to thisgroup of springs I52 are made in accordance with the positions on theticket in which it is desired to have the destination and amountsappear. The upper group of springs I52 have their sockets I54 connectedby wires I56 to the segments I51 of a commutator device shown in Fig. 5.There are two lines of segments I51 and alongside each line is a commonconducting strip I58. A pair of connecting brushes I59 is provided toconnect the segments I51 in succession with the common conductor I 58of. one set and a brush I59A efiects similar connection between thesecond set and its common conductor I58. These brushes are carried byand insulated from an arm I 60 carried by a shaft 22. The timing of theoperation is such that the brushes I59A and I59B make contact with thesegments successively as the type on the various printing wheels arriveat the printing line in the order designated in Fig. 19 opposite thesprings I52. The tracing of a specific circuit will make this clear.

With the plates I50 making electrical connection between the sets ofsprings I52 as shown, a circuit will be completed when the brush I59Acontacts the first segment I51, which is traceable as follows: from thenegative side of line IGI, to left hand conductor I58, brush I59A,uppermost segment I51, wire I56, socket I54, to the left hand plate I50,thence to the uppermost spring I52 and the uppermost printing magnet 81through a wire I62, cam controlled contacts I63, to positive side ofline I64. This circuit is completed as the classification wheel 68presents the designation One way to the printing line and thisdesignation will be printed on the ticket. A second circuit is alsocompleted concurrently which extends from the uppermost wire I 52, tothe second plate I50, the second spring I52, to the second printingmagnet 81, a wire I65, a pair of cam controlled contacts I66, to lineI64. The parts are so timed that the type element for printing theletter A is at the printing line at this time and the character A willconsequently be printed. It will be observed that the fifth plate I50from the left is also connected to the uppermost spring I52 and afurther circuit will also be completed through this plate to the fifthspring I52 to energize its related printing magnet 81 to print thelatter A in this position also. When the brush has advanced to thesecond segment I51, a circuit is completed to print the letter B in itsproper position on the ticket. In this manner, as the brushes I59A andI59B advance, the characters will be printed in the order in which theyare connected to the springs I52; thus, the digits 3, 4, and 5 of theprice will be printed next, and the L and N in order, and near the endof the cycle, the letter Y will be printed, followed by the printing ofthe dollar sign. In a single revolution of the printing wheels,therefore, the various characters will be printed as they pass throughthe printing position.

Iteferring now to Fig. 15, wherein a section of the type wheel group isshown, it will be observed that alternate ones of the wheels 69 aredisplaced a half step with respect to the rest of the wheels. to avoidso-called' shadow printing, that is, the printing of adjacent portionsof characters from the adjoining type wheels together with the printingof the selectedcharacter, and permits the use of the largest possiblecharacters in a smaller space. In order to print correctly from theseoffset type, it is necessary to delay the timing of the wheels whosecharacters are set back a half step an equivalent amount, and it is forthis reason that the two emitter brushes I59A and I59B are provided.

The brush I59A controls the completion of circuits through theclassification and amount printing magnets corresponding to the evennumbered type wheels when counted from the left in Fig.

40 15. These are the printing magnets which are connected to the wireI62, and the contacts I63 in series with thesemagnets are timed to beopen when brush I59B makes connection with its segments I51, and to beclosed when brush I59A contacts its segments. The remaining printingmagnets 81 are connected to the wire I65 and the contacts I66 which aretimed to be closed only when the brush I593 is in contact with itssegments and to be open when the brush I59A makes connection. Thus, forthe printing of the classification One way, the circuit is controlledthrough the brushes I59A and the contacts I63.. At the same instant,brushes I59A also complete the circuit through the fifth plate I50 whichprints the second A in the word Albany. The open condition, of thecontacts I66 at this moment prevents the completion of the circuit forthe first letter A in this word. This circuit is completed a half steplater when 66 the brush I59B contacts the first segment I51 and at thistime the contacts I63 are open and contacts I66 are closed, permittingthe comple tion of the circuit through wire I and printing of the firstletter A from a type wheel whose 65 characters are retarded.

In the diagram of Fig. 19, the brushes I59A and i593 are shown as beingof the same length and their related segments I51 are offset a half Inthe actual construction, for purposes 70 of uniformity, the segments ofthe two sets are actually side by side, but the brushes I59B (see Fig.5) are adjusted to make contact a half step later than the brushes I59A.

Referring to Fig. 6, the shaft 90 has secured thereto an arm I61 which,through a link I68,

, 5 operates a bell crank I69 (Fig. 3) to draw the link I06 toward theleft to release the key lever I34 which has been depressed. This takesplace near. the end of the cycle of operations so that the parts mayreturn to their normal position. 5 A hand leverI10 is provided (Fig. 6)which lies over a pin MI in lever I61 so that the-same may be operatedmanuall A units counter I12 is to the link I08 so that each operation ofthe 10 machine may be counted and, since for each operation a ticketmust be issued,'the counter indicates the totalnumber of ticketsprepared and ejected.

Referring to Fig. 19, the closure of contacts 1 I48 due to the operationof one of the key levers I34 will complete a circuit from line I66,contacts I56, a relay I16, to line I6I. The relay closes its contactsI14a which completes the circlutch magnet 23 and 20 cycle of operationsin the machine, toward the end of which the contacts I68 aremechanically unlatched to permit their opening and interruption of theoperation after a complete cycle has been 5 effected.

Accumulating mechanism The accumulating mechanism is shown in Figs. 5,5a and 5b and comprises a plurality of print- 30 ing wheels I15 to whichgears I16 areattached. The wheels and gears are mounted on a rod I11carried in a frame I18 which is pivoted at I19 and has a rod I passingthrough a slot I6I in an arm I82 secured to a rod I83. When the arm 35I82 is rocked clockwise, the slot I8I will cause the member I18 to rockcounterclockwise and withdraw the gears I16 from engagement with theteeth in sectors I84. The operation is such that as the sectors I03 arerocked clockwise to 40 position the price printing type sectors 61 undercontrol of the corresponding magnets 81, pins I85 in the sectors I03will cause the corresponding sectors I84 to move therewith and takeposition in accordance with the digital value se- 45 lected forprinting. After all the type sectors have been positioned, the gears I16are moved into engagement therewith so that on the return stroke, theamount represented by the positioning of the sectors I86 will be rolledonto the gears. 50 Each gear is provided with the usual carrying toothI86 which is adapted to rock the usual arm I81 clockwise wheneverthcwheel passes through zero. The usual latch I88 is provided to holdthe arm in rocked position; This arm cooperates 55 with a lateralextension I89 of the next higher order sector I89 permitting it toadvance an additional step to enter a uni in its corresponding wheel"whenever the lower order wheel passes through zero. The mechanism forrocking the 60 wheels in and out of engagement comprises linkagedesignated I98 in Fig. 6 which connects the rod I63 to a follower armI9I. The roller is operated by a cam I92 carried by the shaft 22. Aftereach entry into the wheels I15, a printing 65 hammer I93 (Fig. 5) istripped to take an impression from the wheels onto a record strip I96which is provided with suitable spacing mechanism (not shown). HammerI93 is carried on a rod I95 (see Figs. 5a and 5b) to which is also se-70 cured a member I96 which is connected by a link I91 to an arm I98secured to a rod I99. In Fig. 6 the rod has link and lever connection200 to a shaft 20I whose follower arm 202 is op- 4 erated by a cam 285mounted on the shaft 22. At ,7

rock counterclockwise. Near the end of the stroke, latch 204 engages afixed pin 206, causing it to rock to the position shown in Fig.
